Start your mission with DLR.
Our Institute for Aerodynamics and Flow Technology in Göttingen offers a
Aerodynamics and aeroacoustics of subsonic turbulent jets using advanced particle tracking methods and microphone measurements
The PhD candidate will conduct:
- Image processing, multi-pulse STB evaluation and subsequent FlowFit interpolation of the large experimental data set using High-Performance-Computing resources
- Analysis of the fluid mechanical properties of the subsonic turbulent jet flows by one-, two- and multipoint statistics of velocity, pressure and acceleration
- Investigations of coherent structures and related velocity gradients in different regions of the various jet flows
- Determine local 3D causality-correlation functions between microphone signals and velocity fluctuations with a specific focus on the jet shear layer development
- Compare aerodynamics and aeroacoustics of round and chevron nozzles
- Present research results on international conferences and in peer reviewed journals
DLR is offering a unique opportunity to be involved in a fundamental research study at the same time providing comprehensive and interdisciplinary training, with a work programme consisting of both computational and experimental components. The scientific training takes place in a dynamic and excellent scientific environment of modern facilities and under a pioneering, innovative world renowned team and in cooperation with various universities. The candidate must have aerodynamics or fluid mechanics background with a preference for experience in advanced experimental techniques and strong programming skills.
- University degree in engineering or in applied mathematics or in physics or in physics and computer science
- excellent diploma or master's degree, which enables to participate in a German doctoral program. Also candidates nearing completion are invited to apply
- good programming skills in C, C++
- good programming skills in Python and/or Matlab
- some experience in advanced experimental techniques (PIV, Microphone etc.)
- excellent knowledge of mathematical modelling of aeroacoustics and fluid mechanics preferable
- very good German and English language skills
- good knowledge of fluid mechanics is desirable
- ideally knowledge in aeroacoustics
- great interest in fundamental research in aerospace
- great motivation and commitment to science
- willingness to travel (international)
